Summary:A technique fulfills service requests in a system of computers that communicate as nodes within a network. The technique involves sending, in response to an initial service request that requestsa service provided by a primary server node, a mobile agent from the primary server node to an intermediate node. The mobile agent indicates to the intermediate node that a secondary server node is capable of providing the service. The technique further involves intercepting, at the intermediate node, a subsequent service request sent from a client node to the primary server node, the subsequent service request requesting the service, and sending an instruction from the intermediate node to the secondary server node. The instruction instructs the secondary server node to provide the service. The technique further includes providing, in response to the instruction, the service from the secondary server node to the client node. L'invention concerne une technique répondant à des demandes de service dans un système d'ordinateurs qui communiquent en tant que noeuds d'un réseau. La technique comporte l'étape consistant à envoyer, en réponse à une demande de service initiale pour un service fourni par un noeud de serveur primaire, un agent mobile à partir du noeud de serveur primaire vers un noeud intermédiaire. L'agent mobile indique au noeud intermédiaire qu'un noeud de serveur secondaire est capable de fournir le service. La technique comporte en outre les étapes consistant à intercepter, au noeud intermédiaire, une demande de service ultérieure provenant d'un noeud de client et destinée au noeud de serveur primaire, la demande de service ultérieure demandant le service ; et envoyer une instruction à partir du noeud intermédiaire vers le noeud de serveur secondaire. L'instruction commande la fourniture du service par le noeud de serveur secondaire. La technique comporte en outre l'étape consistant à fournir le service, en réponse à l'instruction, à partir du noeud de serveur secondaire au noeud de client.
